The Eminem and Dr. Dre cover of Vibe's 15th-anniversary "Juice" issue is a nod to their original appearance in the mag eight years ago. The issue hits newsstands August 16, and Dre began by answering the question on many fans' minds: Did he know Detox would take this long?

"Absolutely not. I thought it would take, at worst case, a couple of years," the super-producer said. "For example, actual work time on The Chronic was nine months, and actual work time on my last album, 2001, was about 10 months. The actual work time on this album is about half of that, where I'm seriously focusing on it. There is always something coming up. Like signing talent, old and new."

The California icon also talked about the recent leak of his duet with Jay-Z, "Under Pressure."

"[That] was a little bit more frustrating, because at least 'Crack a Bottle' had a hook on it," Dre said of a previous leak. "I wouldn't be as mad at a leak if the song was done.

"I'm not mad at the fans," he continued. "I'm mad at the person that leaked the sh--. I have no idea how it got out. It's not even worth looking to see who did it. It happens. The most painful part about it is that I'm passionate about what I do, so people should hear it in the right form. Somebody actually hacked into our e-mails, so that made our red flags go up. We're in a new age, and that's a sign: 'Wake up, mother----er. You have to be more careful with your sh--.' That's all there is to it. I know what's up now."

As for an album of instrumentals, Dre said it's definitely on deck.

"Oh, yeah, that's in the works," he said. "An instrumental album is something I've been wanting to do for a long time. I have the ideas for it. I want to call it The Planets. I don't even know if I should be saying this, but f--- it. [Laughs.] It's just my interpretation of what each planet sounds like. I'm gonna go off on that. Just all instrumental. I've been studying the planets and learning the personalities of each planet. I've been doing this for about two years now, just in my spare time, so to speak. I wanna do it in surround sound. It'll have to be in surround sound for Saturn to work."
